Abstract

1417096 Substation equipment PIONEER ELECTRONIC CORP 25 Jan 1973 [26 Jan 1972] 3957/73 Heading H4K In a telephone answering machine in which an incoming message can be recorded whilst the initial announcement message is still being transmitted, the endless loop answering tape T1 is provided with two spaced heads H3, H1. The output from the first head H3 in the direction of tape movement is amplified at 5 and is effective whenever it exceeds a predetermined limit to actuate switch 6. The latter enables an amplifier 1 after a delay equivalent to the separation d between the two heads so that the signal portion exceeding the limit (and thus assumed to be a recorded message signal) is reproduced into the telephone line 3. Any incoming message on line 3, as well as any reproduced message is recorded on tape T2. Since the announcement circuitry is only connected to line during the actual time that there is a valid signal to be transmitted, any incoming message occurring during the overall announcement period is only swamped during this time.
